The heater water tank fan cannot be started.

The situation that the water tank does not turn can be investigated one by one according to the following three points: First, whether the water temperature meets the requirements: Most of the current automobile radiator fans use electronic temperature control, so generally, the fan will start to rotate normally only when the water temperature in your car reaches the required temperature. If the temperature is too low, the radiator fan will not turn. Therefore, when your car radiator fan does not turn, first check whether the water temperature meets the requirements. 2. Relay failure: If the water temperature meets the requirements and the radiator fan of the car still can't work, then there may be something wrong with the relay of the fan. If the relay fails, the cooling fan of the car will not work. Third, there is something wrong with the temperature control switch: if there are no problems in the above two aspects, then you should check the temperature control switch. Sometimes there will be some faults in this place, which will also have a certain impact on the operation of the radiator fan of the car, so you should also pay attention to the inspection.
